Lh Wolf 1964 66 Journal August 19 Tehuantepec, Oaxaca, Mexico Up at 0515. Drove out to 2 1/2 mi. E. of town when stopped for breakfast along road. I stayed here to observe Anemphila rufiganda + Dick went back to where he collected yesterday. The area I worked in is a grassland with shrubs & tree cover which at times reaches closed canopy, but averages 50% or less closed. Most of the trees are species of Acacia. There are some Celtis, few Prosopis, plus other legumes. The grass forms a closed cover + there aren't many weeds. Apparently there are few cattle grazing here & the grass is 6-12 inches tall. rufiganda was not common anywhere, but did occur at edges of Acacia - shr. thickets & out into grassland. Seemed to take refuge in thickets so may occur in more open areas than observed. Luminclerus heard calling from areas where closed canopy thickets reached larger proportions (in area) + Acacia was less dominant. Partly cloudy + sleety until 0800 when sun came out. Wind picked up by 0730 + was 5-10mph + gusts to 15+ by 0830. Saw stink out & active at 0700. Back to town where went to market. Spent afternoon preparing specimens. After supper Dick (car) going out sight driving when discovered that car wouldn't start, lights seem to be low + the starter doesn't make contact. Get a Texan here to push us to get it started.
